[ 12 ] Notes
1) This device use IC.
Please take necessary precautions to prevent damage due to electrical static discharge.
2) We recommend placing a 0.01 to 0.1 µF capacitor closely between Vcc and GND to obtain stable operation
and protest against power line ripple.
3) Vcc and GND pattern shall be as large as possible so that high frequency impedance shall be small.
4) SEIKO EPSON CORPORATION cannot recommend to put filtering element into power line so as to reduce
noise. Oscillator might be unstable oscillation because high frequency impedance of power line become
higher.
When use filtering element, please verify electrical construction and or element's spec.
5) SEIKO EPSON CORPORATION doesn’t recommend to power on from intermediate electric voltage or
extreme fast power on. Those powering conditions may cause no oscillation or abnormal oscillation.
6) Start up time (0 →90 % Vcc) of power source should be more than 150 µs.
7) Please design the two output lines as short as possible.
A long output line may cause irregular output.
8) Other high level signal lines may cause incorrect operation, so please do not place high-level signal line close
to this device.
9) This device contains a crystal resonator, so please do not expose to excessive shock or vibration.
10) An automatic assembly is available, however, the internal Crystal resonator might be damaged in case
that too much shock or vibration is produced mechanically.
Be sure to check your machine condition in advance.
11) Ultrasonic cleaning can be used on this product, however, since the oscillator might be damaged
under some conditions, please exercise caution in advance.
12) We recommend to use and store under room temperature and normal humidity to secure frequency
accuracy and prevent moisture.
13) The metal part of the surface (metal cap) is connected to GND #3 pin.
Please take necessary precautions to prevent short circuit to GND by contact with the metal cap.
14) Side leads (A) to (D) are connected to IC internally.
Therefore be careful for short or a fall of insulation resistance etc.
15) When not use OE pin connection, please use connecting to Vcc.
We recommend installation a resistor in between to mitigate effect by surge etc.

OUT-13-0473 rev.2
13
16) Recommendation reflow times are less than 2 times.
When there was a soldering error, please do alteration with a soldering iron.
In this case, the iron ahead is equal to or less than +350 °C and asks within 5 s.
In case that this device is reflow soldered on the back side of your circuit board, please carefully verify the
device is properly secured to prevent coming detached from card.
[About soldering method]
17) Connect output terminals to load resistance individually to prevent destruction the internal IC.
18) Aging in the frequency tolerance is from environmental tests results to the expectation of the
amount of the frequency variation.
19) Please do not place signal lines and supply voltage lines on the area, its internal layers, and the back side of
where the oscillators are soldered. This may affect the performances of the oscillators.
20) We will announce the discontinuance and switch to our successor before six months or more.
